我正在Webforms项目中升级到TweetInviAPI 4.0.0。由于TweetInviAPI 4.0.0是.net Core库，因此遇到以下错误：
Could not load file or assembly 'System.Runtime, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
我已阅读到安装NETStandard.Library.2.0.3是一种解决方案，但对我而言不起作用。
